  Initial overclocking results

  I'm not going to include a complete chart of overclocking results for RX Vega right now, mostly because I don't have them. I did some preliminary testing, and things are far more interesting on the Vega 56 card, as you'd expect. Simply raising the HBM2 clockspeed to 930MHz base (close to the same as the Vega 64's 945MHz) and cranking the power limit to 50 percent improved performance to where Vega 56 is effectively tied with Vega 64. Going further, I toyed with the percentage overclock slider and managed to push it up 20 percent higher. In both cases, system power draw while gaming basically matched the Vega 64—480W at the outlet.

  Here's the weird thing: in limited testing, all that added clockspeed did very little for performance. And yes, the clockspeed did go up (along with power draw), as Radeon Settings showed sustained clockspeeds of around 1900MHz. But again, this is only limited testing

  Memory bandwidth bottleneck?

  Találgatunk, aztán majd úgyis kiderül..
